As topic states, happened last night on the way to pick up some more G40 BBS wheels and as I was driving along this skinny country road, I pulled in to let a car through... As I pulled in and stopped she started to rev and was then idling at like 2K and sat there
My heart sank
I revved her very lightly and gently (as some would to warm a car) and let off and nothing changed
I did the same again and she returned to normal
Why would she have done this/what would have coursed her to do that?
